There’s an old Arab proverb that it is easier to get into a hole than to get out of it. When it comes to climate, clean energy and carbon policy in Australia, it is clear we are in a deep hole.

Investment in renewables has crashed by some 88% in Australia, precisely at the time when global clean energy investments have overtaken fossil fuel investments. And it is a matter of fact that since the removal of laws that capped and priced carbon, emissions from the electricity sector have rebounded to levels not seen since Malcolm Turnbull last led the Liberal Party.
